Struct scylla::frame::response::result::Row

pub struct Row {
    pub columns: Vec<Option<CqlValue>>,
}

Fields

columns: Vec<Option<CqlValue>>

Implementations

impl Row

pub fn into_typed<RowT>(self) -> Result<RowT, FromRowError>

where RowT: FromRow,

👎Deprecated since 0.15.0: Legacy deserialization API is inefficient and is going to be removed soon

Allows converting Row into tuple of rust types or custom struct deriving FromRow

Trait Implementations

impl Debug for Row

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Row

fn default() -> Row

Returns the “default value” for a type.

impl<'frame, 'metadata> DeserializeRow<'frame, 'metadata> for Row

While no longer encouraged (because the new framework encourages deserializing directly into desired types, entirely bypassing CqlValue), this can be indispensable for some use cases, i.e. those involving dynamic parsing (ORMs?).

fn type_check(_specs: &[ColumnSpec<'_>]) -> Result<(), TypeCheckError>

Checks that the schema of the result matches what this type expects.

fn deserialize( row: ColumnIterator<'frame, 'metadata>, ) -> Result<Row, DeserializationError>

Deserializes a row from given column iterator.

impl PartialEq for Row

fn eq(&self, other: &Row) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
